Harvey Friedman, in conversation with me (confirmed by Shapiro), had always taken a similar view. 3 I too had always felt that the issue of Church’s thesis wasn’t one that was obvi-ously not a mathematical one, susceptible of proof or disproof, but could be a

And this is why this brief note comes out. Note that, there is no proof for Church-Turing Thesis. The thesis is more like an empirical statement.
